This section mainly on the advantages and disadvantages of JMeter and LoadRunner summary, if there are deficiencies, please correct me, greatly appreciated!
At the same time, I also have to admit that in comparison with JMeter and LoadRunner, I personally do favor the JMeter (free, open source, cross-platform, flexible expansion). In this section, you can think of the ideas described in this section as my personal referral to the open source JMeter. In fact, JMeter is now one of the automated testing tools I have been learning, and it has indeed become one of the main tools of my daily automated testing, and LoadRunner because of its high cost and hardware and software load, I am a little behind, but also can be said to be powerless.
Similarities between JMeter and LoadRunner:
- JMeter and LoadRunner architectures are basically the same. Through intermediary agents, monitoring & collection of concurrent client discovery instructions, generate scripts, and then send to the application server, and then monitor the server feedback results of a process
- The JMeter also has distributed intermediary agent functions. This distributed factoring means that multiple agents can be set up in different PCs, remotely controlled by using multiple machines to run so-called agents to share load generator self-pressure, and take this to get a larger number of concurrent users
JMeter advantages relative to LoadRunner:
- Open source Free: JMeter is a free open source software that uses it without paying any fees
- Cross-platform: open source software for Java development
- Compact: Very small compared to the large LR (LoadRunner 4GB), it is very compact (the latest version 2.12 is only about 33M)
- No install: But requires a JDK environment because it is a tool developed using Java
- JMeter can do functional testing of Web programs, using samples in JMeter, can do gray-box testing, LoadRunner mainly used for performance testing
- Powerful: JMeter design is just a simple Web performance test tool, but after a period of update extension, can now complete the database, FTP, LDAP, WebService and other aspects of testing
- Flexible expansion: As a result of its open source, can be obtained two development, packaging, optimization, the function of the customized, so that it can better adapt to test requirements, or according to their own needs to expand its capabilities, you can write your own expansion pack (jar), put in {apache-jmeter-2.12\lib\ EXT} directory, request references via Java
JMeter with respect to LoadRunner:
- The interface is not beautiful (open source typical features)
- Results data presentation is insufficient
- Result analysis Ability not loadrunner detailed
- There are some gaps in recording function and debugging environment
- JMeter does not have IP spoofing, IP spoofing refers to multiple IP addresses on a PC to be assigned to concurrent users. This feature is useful for simulating a more realistic customer environment
- JMeter non-commercial software, no professional technical support, because of the late start of the corresponding learning materials less, but with the growing use of JMeter groups, I believe this situation will be greatly improved.
Finally, due to the personal understanding of JMeter and LoadRunner, if there are deficiencies in this article, please inform. At the same time, I hope this article will not arouse the loadrunner of the strong advocates of the offensive, if there are offensive, please forgive me! After all, existence is meaningful. If there are any different views, I very much welcome you to discuss the rational message, thank you very much! ^_^
